TERMINAL MODE
When you switch the unit on, the cursor flashes in
the first line, indicating that the display is ready for
operation. All the incoming characters are
displayed in ASCII format on the terminal
(exception: CR,LF,FF,ESC,’#’). The prerequisite
for this is a working protocol frame or a deactivated
protocol (see pages 10 and 11).
Line breaks are automatic or can be executed by
means of the ‘LF’ character. If the last line is full, the
contents of the terminal scroll upward. The ‘FF’
character (page feed) deletes the terminal.
The character ‘#’ is used as an escape character
and thus cannot be displayed directly on the
terminal. If the character ‘#’ is to be output on the
terminal, it must be transmitted twice: ‘##’.
The size of the terminal-window can be set by
command 'ESC TW'.
Attention: Graphic commands are able to draw
inside terminal window. For example 'ESC DL' will
delete terminal window, too.
USING THE SERIAL INTERFACE
The operating unit can be programmed by means of various integrated commands. Each command
begins with ESCAPE followed by one or two command letters and then parameters.
There are two ways to transmit commands:
1. ASCII mode
- The ESC character corresponds to the character ‘#’ (hex: $23, dec: 35).
- The command letters come directly after the ‘#’ character.
- The parameters are transmitted as plain text (several ASCII characters) followed by a separating
- Strings (text) are written directly without quotation marks and concluded with CR (hex: $0D) or LF
2. Binary mode
- The escape character corresponds to the character ESC (hex: $1B, dec: 27).
- The command letters are transmitted directly.
- The coordinates xx and yy are transmitted as 16-bit binary values (first the LOW byte and then the
- All the other parameters are transmitted as 8-bit binary values (1 byte).
- Strings (text) are concluded with CR (hex: $0D) or LF (hex: $0A) or NUL (hex: $00).
No separating characters, such as spaces or commas, may be used in binary mode.
The commands require no final byte, such as a carriage return (apart from the string $00).
